UNITED STATES WILLIAM F. RICHARDSON, OF PORTSMOUTH, VIRGINIA.

WATER HEATER. l

Application filed April 17, 1925.

To all whom t may concern.'

Be it known that I, VILLIAM F. RICHARD- son. a citizen of the United States residing at Portsmouth, in the county of Norfolkand State of Virginia, have invented a new and useful lVater Heater, of which the following is a specification.

This invention relates to water heating apparatus, one of its objects being to provide means whereby it becomes unnecessary to utilize a coil within a heating furnace in order to heat water designed for domestic purposes.

A further object is to provide a heater which can utilize either the water or steam of a heating system for the purpose of heating water for domestic use or'can employ a gas burner or the like while the furnace is not in use.

Another object is to provide a water heater which can be easily installed and is very efficient in operation.

With the` foregoing and other objects in view which will appear as the description proceeds the invention resides in the combination and arrangement of parts and in the details of construction hereinafter described and claimed, it being understood that changes in the precise embodiment of the invention herein disclosed may be made within the scope of what is claimed without departing from the spirit of the invention.

In the accompanying drawings the preferred form of the invention has been shown.

In said drawings7 I 'Figure 1 is a central vertical section through the water heater, theA same being shown connected to a furnace and to a domestic boiler.

Figure 2 is an enlarged section on line 2-2 Figure 1.

Referring to the figures by characters reference 1 designates a furnace of the hot water type and Figure 2 designates an ordinary domestic boiler. The heater constituting the presentinvention is adapted to be connected both to the furnace and the boiler. This heater includes a drumv 3 having a base 1 adapted to be supported in any suitable manner, and fitted Within the base 4- is a burner 5 having a supply pipe 6 leading thereto. This burner is adapted to use gas as a fuel although it is to be understood that an oil burner may be employed under some conditions. The upper end. of

Serial No. 23,897.

thedruniv 3 has a hood 7 which is conical and provided with an outlet flue 8.

Extending longitudinally within the drum 3 at the centerthereof is a flue 9 having flared ends 10 and l1. The lower liared end 11 extends tothe lower margin of the drum 3 while the upper flared end 10 of the flue extends to thev upper margin of the drum. Thus thefflue, and its flared ends permit the free flow of hot combustion products upwardly through the drum to the outlet iue 8. l

Arrangedwithin the drumis a sleeve 12 spaced from and concentric with the flue 9, this sleeve having a flaredupper end 13 spaced from the flare 10 and extending toy the wall of the drum 3. It also has a flared lower end 14 spaced fromthe liare 11 and extending to the wall of the drum. Flue'9 with its ends cooperates with sleeve 12 and its flared ends to provide a Water jacket 15 which extends around the flue 9, A heating chamber 16 is also provided Within the drum 3 and around sleeve 12. This chamyber 16 is adapted to receive and deliver water or steam through pipes 17 which are connected tothe hot water or steam pipes 18 of furnace 1. Consequently during the operation of the furnace 1 the Water contained in the chamber 16 will be maintained at approximately the same temperature as that in the pipes and radiators of the heating system connected to furnace 1.

The domestic boiler 2 vis connected, by e pipes 19, to the upper and lower ends of the water jacket l5. Thug wateradmitted to the boiler 2 in the usual way will circulate through and be heated in the water jacket, the temperature thereof being raised by the hot water or steam supplied t0 chamber 16 from the pipes 18. As long as the heating system'is in operation an ample supply of Water for domestic purposes Will loe maintained in the boiler 2 as will be obvious. If, however, the use of the heating plant is stopped or else the temperature is so re- `duced that only a very low heat is maintained, the burner 5 can be used to raise the temperature of the Water in the jacket 15.` Duringy the use of this burner the hot product of combustion will `flow along theflared end 11. andinto flue 9 and then outwardly through the hood 7 to flue v8'. During its passage through the flue9 and along the "nend 11, the products of combustionv Will quickly raise the teinneratine of 'the parte contacted thereby and also correspondingly rlfaise the temperature of the contents of the Water jacket. Y

It will he anare'nt that o z/ utilizing a dolnastic water healer such as described it heconies possible to provide an ample supply of water 'for domesticA purooses at all tin'ies, the heating system connected to the turna "e l. being` utilized during oold weather 'or heating' the dannostie water while the gas burner 5 is utilized during; moderate and warni weather. he principle'advantage of this construction is the elimination of water coils which are liable to break in 1he fire Ybox of the furnace and require the drawing,r

heater including` a 20 drum, a hood thereon having an outlet, a

central longitudinal line having Vflared ends extending' to the wall oi tne drinn, a sleeve mounted within the druin and having Aflared ends extendingI to the walls oi? the drumt` said sleeve and its ends beingl spaced 'lroin the flue and its ends and cooperating therewith to provide a water jacketi there being` a coingartinent surrounding the sleeve and out of connnunicafion with the water jacket, said con'ipartinent having an inlet and an outlet, there being` an inletr and an out let to the water jacket, and a burner be neath the drinn for directing` products of combustion into the Yflared lower end of the flue.

ln testimony that l ele-ini the 'foregoing as my own7 l have hereto affixed niy signa ture.
